Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

From Disney World to the smartphone in your pocket, fingerprint scanners have become commonplace these days. Even budget phones sport the tech, sometimes alongside other biometric unlocking options ...

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...

Many billions of mechanical buttons in cell phones, cars audio systems, notebooks, PCs, white goods, and industrial applications have been replaced with capacitive sensing buttons. The use of ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...
